the International Symposium on Conservation of Native European Freshwater Crayfish will be held in Olot, Girona (Spain) from 23-25 September 2015. Registration has been extended to 15 July 2015.

The conservation of native crayfish is one of the major challenges in European inland waters, since most species are endangered by many factors, but specifically by introduced species and pests. This symposium will focus on recent research advances, and also on management strategies and specific experiences focused to achieve a long-term conservation of our native freshwater decapods.

Welcome the latest member of the parthenogenetic club, the smalltooth sawfish!

This case is interesting not only because it adds yet another case of facultative parthenogenesis to the list, but because it’s one of the few times facultative parthenogensis has been seen in wild populations. The bad news is that this might be because the sawfish is endangered: the population is so low that the fish are resorting to “last gasp” reproductive efforts.
